ABSTRACT

An image forming apparatus includes a web relay unit and, in a case where a file input field exists in screen information acquired from a web service provided by the web server capable of communicating via a network, the web relay unit extracts a file downloaded from another web service which can collaborate with the web service from a storage device, converts the file input field included in the screen information into a selection box, and transmits, to the web browser, screen information in which the extracted file is set to the option of the selection box.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an image forming apparatus, an information processing method, and a storage medium.

2. Description of the Related Art

Until now, it has been known that an image processing apparatus is connected to an external server on a network to use a service provided by the external server.

According to the description of Japanese Patent Application Laid-Open No. 2007-128370, for example, it has been known that image data generated by reading an image on a document is transmitted to a document management server on a network and registered in a document management database on the document management server side.

It has also been known that, when the image processing apparatus uses the external service, an external server has a web server function and the image processing apparatus uses a web browser to connect with the external server.

In this case, the web browser of the image processing apparatus requests the external server to transmit information about an operation screen and an application of the external server transmits Hyper Text Markup Language (HTML) data for displaying the information about the operation screen in response to the request from the image processing apparatus. The web browser of the image processing apparatus analyzes the received HTML data and displays the information about the operation screen based on the description of the received HTML data.

However, as described above, when the image processing apparatus uses the web browser to connect with the external server and uses the external service provided by the external server, the following problems may be caused.

In a case where a multifunction peripheral (MFP) with a scanner function and a printer function uses the web browser to connect with the external server, for example, operation-screen information provided by the external server may not be normally displayed. This is because the web browser of the MFP does not always conform to all the HTML data provided by the external server.

In general, if the description of “<INPUT type=“file”>” exists in the HTML data, the web browser operated on a personal computer (PC) displays the input field of a file name and a button “Browse . . . ”. When the web browser detects that the button “Browse . . . ” is pressed, the web browser displays a file selection dialog. A user may select any file to be transmitted to the external server using the file selection dialog. The web browser of the MFP can display the input field of a file name and the button “Browse . . . ”, however, even if the web browser of the MFP detects that the button “Browse . . . ” is pressed, the web browser of the MFP does nothing about processing. This is because the web browser of the MFP does not correspond to a function to display a file selection dialog.

The present invention has been made in view of such a problem and has such an object that, in a case where a file input field exists in screen information acquired from a web service provided by the web server, the file input field is converted into a selection box which can be processed by the web browser of the image processing apparatus and a file downloaded from the web service which can collaborate with the web service is set to an option of the selection box.

SUMMARY OF THE INVENTION

According to an aspect of the present invention, an image processing apparatus includes a web browser and a web relay unit configured to relay communication between a web server capable of communicating via a network and the web browser, wherein, in a case where a file input field exists in screen information acquired from a web service provided by the web server capable of communicating via the network, the web relay unit extracts a file downloaded from another web service which can collaborate with the web service from a storage device, converts the file input field included in the screen information into a selection box, and transmits, to the web browser, screen information in which the extracted file is set to an option of the selection box.

DESCRIPTION OF THE EMBODIMENTS

Various exemplary embodiments, features, and aspects of the invention will be described in detail below with reference to the drawings.

The exemplary embodiment of the present invention is described below with reference to the attached drawings. The exemplary embodiment is described using an example of the processing in which printing is performed with a web server providing a customer-related information management function in corporation with a web server providing a form generation function.

FIG. 1 is a schematic diagram illustrating an example of a configuration of an image forming system.

As illustrated in FIG. 1, a multifunction peripheral (MFP) 110, a web server 120, and a web server 140 are connected to communicate with one another via the Internet through local area networks (LANs) 100, 130, and 150 connected thereto respectively.

The MFP 110 has a copy function. The MFP 110 also has a data transmission function to read a document image and transmit the read image data (also referred to as document data) to an apparatus designated on the LAN 100 using a file transfer protocol (FTP) or a server message block (SMB) protocol. The MFP 110 is also capable of creating an e-mail with an image as an attachment file and transmitting the e-mail using an e-mail server (not illustrated). The MFP 110 is an example of the image forming apparatus.

The web server 120 provides the customer-related information management function as a web service. The web server 120 has a database function to manage the customer-related information. The web server 120 has also an operation screen generation function to operate the database function. The web server 120 can transmit database information in response to a request received from the outside via the operation screen.

The web server 140 provides the form generation function as a web service. The web server 140 has the form generation function. The web server 140 has also an operation screen generation function to operate the form generation function. The web server 140 creates a file in a portable document format (PDF) by superposing data on a template, which is a form base, in response to a request received from the outside via the operation screen. The web server 140 can transmit the created file as a response.

The system in the present exemplary embodiment is not limited to the number of the above components.

FIG. 2 is a block diagram illustrating an example of a hardware configuration of the MFP 110.

As illustrated in FIG. 2, the MFP 110 includes a scanner unit 112, a printer unit 113, a controller 200, and an operation unit 111.

The scanner unit 112 converts image information into an electric signal by inputting reflected light obtained by exposure-scanning an image on a document into a charge coupled device (CCD) sensor. The scanner unit 112 converts the electric signal into a luminance signal including red (R), green (G), and blue (B) colors and outputs the luminance signal as digital image data to the controller 200. The document is loaded to a document feeder. When a user instructs the controller 200 to start reading via the operation unit 111, the controller 200 instructs the scanner unit 112 to read the document. The scanner unit 112 receives the instructions, feeds the document one by one from the document feeder, and reads the document. The document may be read such that the document is placed on a glass plate (not illustrated) and an exposure unit is moved to scan the document, instead of an automatic feeding system using the document feeder.

The printer unit 113 is an image forming MFP for forming the image data received from the controller 200 as an image on a sheet of paper. In the present exemplary embodiment, the image forming method is meant to be an electrophotographic method using a photosensitive drum and a photosensitive belt, but not limited this.

The controller 200 is electrically connected not only to the operation unit 111, the scanner unit 112, and the printer unit 113, but also to a LAN 100 via a network I/F 206. In other words, the controller 200 is connected to other devices via the LAN 100. This enables communication by the HyperText Transfer Protocol (HTTP).

A central processing unit (CPU) 201 totally controls access to various MFPs which are being connected thereto and access from other MFPs based on control programs stored in a read only memory (ROM) 202. The CPU 201 also totally controls various processing performed inside the controller 200. The control includes the execution of a program for realizing the flow chart described later.

The operation unit I/F 205 receives image data displayed on the operation unit 111 from the system bus 211, and outputs the image data to the operation unit 111 and information input from the operation unit 111 to the system bus 211 as well.

The network I/F 206 is connected to the LAN 100 and the system bus 211 to input and output information.

A scanner I/F 207 performs correction, processing, and editing on the image data received from the scanner unit 112. The scanner I/F 207 has a function to determine whether the received image data is either a color document or a monochrome document, and either a text document or a photographic document.

An image processing unit 208 performs direction conversion, image compression, and decompression processing on the image data. The image processing unit 208 can synthesize the images stored in the HDD 204 into one image.

A printer I/F 209 receives the image data sent from the image processing unit 208 and provides the image data with image formation while referring to attribute data attached to the image data. The image data after the image formation is output to the printer unit 113.
